Pengendalian Laju Korosi Baja Dalam Air Laut Dengan Menggunakan Proteksi Katodik Metoda Anoda Korban

---

ABSTRACT
Cathodic protection is a metal surface protection system against corrosion by direct current (DC ) from an external source to protect metal surfaces from corrosion. In this study, which the protection was employed of voltaic series sacrificial anode method, where the metal has a lower potential is used as sacrificial anodes in order to controlling carbon steel of corrosion. This research was conducted by using ASTM A36 steel in Bengkalis seawater with immersion lengths of 10, 15, 20 and 25 days by using sacrificial anodes of Al and Zn. The purpose of this research was to study the effect of cathodic protection in controlling the corrosion rate of carbon steel, determine the effectiveness of the sacrificial anode, and determine the best distance from the anode to the cathode. The design of the study was done by varying the type of anodes in the form of Al and Zn, the anode to cathode distances were 1 cm, 2 cm, 3 cm. Data was processed by using weight loss method with unit (mpy). The best protection occured at 10 days immersion, by using Al anode, the lowest corrosion rate was 1.448 mpy, and using Zn anode, the lowest corrosion rate was 1.601 mpy. In this research obtained the best effectiveness for carbon steel was protected by Al and Zn anode with a distance of 1 cm was 79.1% and 76.9%.
Key words: cathodic protection, corrosion rate, seawater, sacrificial anode
